摘要： A method of controlling a transmission park control system for a vehicle comprises receiving a shift request from a transmission controller, wherein the shift request is not completed by the transmission and reporting the shift request from the transmission controller to the transmission park control system. Various vehicle sensors are monitored to detect motion of the vehicle. Detected motion and the shift request are compared to determine that a transmission park control brake action is desired. A brake system is requested to apply one of an electronic parking brake and/or a vehicle service brake to bring the vehicle velocity to zero and hold the vehicle velocity at zero.

摘要： A control system to generate a yaw torque of an all-wheel drive vehicle comprises a brake control module 18. The brake control module 18 determines the desired powertrain torque 44 for the vehicle 10 based upon a plurality of factors including available torque from the powertrain. The brake control module 18 determines a first torque 44 and a second torque 26, wherein the first torque 44 and the second torque 26 are combined to provide the total desired yaw torque 49 of the vehicle 10. The first torque 44 is generated between wheels of the vehicle 10 by applying torque 44 from the powertrain 14 to different wheels 21 of the vehicle 10 and the second torque 26 is generated by applying different braking torque from a braking system 16 of the vehicle 10.

摘要： An air suspension system which includes the ability to adjust the working air volume, pressure, and spring rate of one or more air springs to reduce or eliminate various types of vehicle oscillations. Switchable or variable volume air spring assemblies have the ability to change air spring volumes, which results in changes in air spring rates, and therefore changes in normal loads applied to each wheel. Changes in wheel normal loads change wheel traction (slip) and vehicle dynamics (pitch, roll, yaw displacement, rate and acceleration). The spring rate of one or more of the air spring assemblies is adjusted automatically when a vehicle oscillation is detected. This vehicle oscillation is calculated from the raw vehicle signals, or another vehicle module may detect the oscillation and send a command to the air suspension module to change the spring rates. This changes the natural frequency of the vehicle, dampening the oscillation.

摘要： A vehicle air spring suspension system includes multiple air springs. Each air spring has at least one volume. A valve is fluidly arranged between at least two volumes of the at least one volume of the air springs. The valve is movable between open and closed positions in response to an input. The at least two volumes are fluidly coupled with the valve in the open position. The at least two volumes are fluidly decoupled with the valve in the closed position. At least one vehicle sensor is configured to detect a vehicle attitude condition. A controller is in communication with the valve and the at least one vehicle sensor. The controller is configured to provide the input and selectively adjust the air springs to change the vehicle attitude by raising and/or lowering at least one vehicle wheel relative to a vehicle chassis in response to the input.

摘要： An air suspension system which includes a Dynamic Load Transfer (DLT) function. DLT is a process of transferring vehicle load, or varying normal loads applied to each wheel of the vehicle, using switchable volume or variable volume air spring assemblies. Switchable or variable volume air spring assemblies have the ability to change air spring volumes, which results in changes in air spring rates, which result in changes in normal loads applied to each wheel. Changes in wheel normal loads change wheel traction (slip) and vehicle dynamics (pitch, roll, yaw displacement, rate and acceleration). Each air spring assembly may have multiple volume air chambers that are switched “on” and “off,” a variable volume air chamber, or the air spring assembly may be coupled with other air springs, or air chambers, that are switched or varied.
